IMPROVEMENT IN UPRIGHT BOILERS FOR RANGES, STOVES, &0.

Specification forming part of Letters Patent No. 165, E05, dated June29, 1875; application filed August 14, 1374.

To all whom it may concern Be it known that we, JAMES LAWTON and JAMESA. GIBSON, of the city of Cincinnati and State of Ohio, have inventedcertain new and useful Improvements in Upright Boilers for Ranges,Stoves, &c., of which the following is a specification Our improvementspertain to upright boilers for ranges, stoves, &c.

Where water is used containing mud or other impurities'there is greatnecessity of frequent cleaning, for the reason that a portion of theimpurities will lodge in the bottom of the boiler, and a part will passinto the heater-pipe and be carried to the heater, filling it up. andcausin git to burn out. Where hard water is used the lime or otherminerals form in scales, oftentimes covering the orifice of theheater-pipe, and preventing the egress of water from the boiler to theheater.

We obviate these difficulties by the elongation of the pipe conveyingthe Water into the heater out of the boiler, and also by placing theinlet-pipe directly over the heater-pipe, so that there may be a steadyflow of water into the heater, and back to the boiler withoutinterruption.

In the accompanying drawing, the figure represents a vertical section ofthe boiler, takelnthrough the center of the pipes connected therewith.

A represents an upright boiler of the usual form for ranges, stoves,860. B is a handhole, closed by means of a flanged plate, a, throughwhich access can be had to the inside of the boiler when cleaning isnecessary. D is the heater-pipe, entering at the bottom of the boiler,and leading to the heater in the stove or range. This pipe rises in thebottom of the boiler, almost touching the bottom end of the feed-pipe. Eis the inlet or feed pipe, entering at the top of the boiler, and comingdown nearly to the heater-pipe D. It is perforated in the lower end ata: a w m with small holes, and with large orifice at X. F is thereturn-pipe, entering in the side of the boiler. This is the pipe whichreturns the water from G is the effluent ter is drawn off throughetfluent pipe G, a new supply of water enters the boiler through pipe E.A portion of this Water enters the boiler through the perforations inthe sides of the orifice of pipe E, and issues forth in spray, causing achurning motion in the water in the boiler, thus preventingincrustations of mud and other impurities from being formed on the sidesofthe boiler. The main portion of the Water passes through the largeorificein thelower end of the pipe E, and spouts directly into the mouthof pipe D, thereby, even though there be no fire in the stove, causingthe water in the latter pipe to flow through the heater, and return tothe boiler through the return pipe F, thus keeping the heater free fromsettlin gs and impurities which would otherwise accumulate when therewas no fire in the stove, and consequently no circulation of waterthrough the heater, caused by the heating of the same.

Pipe D, coming up higher in the boiler than pipes of this descriptionhave heretofore done, is above any mud which may collect in the bottomof the boiler, thereby preventing any deposits from entering pipe D andstopping it up, or the heater, to which it is connected. All danger,therefore, of explosion or burning out of the coil in the heater isobviated, and the disagreeable rattling noise caused by the stoppage ofthe pipe.

What we claim as new, and desire to secure by Letters Patent, is

The combination, in an upright boiler, of feed-pipe E and heater-pipe D,the pipe E being placed directly over pipe D, as for the purposes setforth.
